NEW QUESTION # 17
AC is more easily distributed than DC. This is because:
- A. DC needs wires to be totally insulated, while AC wires can be bare, hung from insulator on pylons.
- B. Wires have less resistance if they are carrying AC
- C. AC can be transformed from a low voltage to a high voltage and back again with a transformer. DC cannot.
- D. AC can be transmitted using lighter wires.
Answer: C
Explanation:
Explanation
AC can be transformed from a low voltage to a high voltage and back again with a transformer, while DC cannot. This makes it easier to distribute AC electricity over long distances and is why it is used more widely than DC electricity. A and B are also true, as wires carrying AC can be bare and don't need to be totally insulated. Wires have less resistance when carrying AC electricity, which is why it is more efficient than DC.
NEW QUESTION # 18
If a waveform period is determined to be 10 microseconds in duration, what is the frequency of the signal?
- A. 100 kHz
- B. 100 Hz
- C. 10 kHz
- D. 1000 Hz
Answer: A
Explanation:
Explanation
Frequency is the inverse of period, so to calculate the frequency of a signal with a period of 10 microseconds, you would divide 1 by the period, which is equal to 100 kHz.
